• blood worms in Anglo-Saxon
• worms are used as live bait for recreational fishing at sea.
• Live seaweed packaging systems are already known for their air transport. Such systems consist of large cardboard boxes containing a bottom of newspaper covered with a litter of fresh and moist algae, allowing transport of the order of one hundred to one hundred and thirty live worms. per box.
• a refrigerant is introduced into the carton during filling to preserve a certain freshness during transport that lasts about sixty hours before reaching the point of sale in a fishing store.
• the present invention aims to overcome these disadvantages. For this it starts from an entirely new idea within the framework of the packaging of live sea worms of this type for air transport, namely to envisage a conditioning itemized by small boxes or trays at the source, that is to say Nearly at pick-up with average cost per worm lower than or equal to current cost, while guaranteeing higher quality worms.
• the present invention aims to provide a device and a semi-automatic packaging process better than those previously known to the requirements of practice, particularly in that it allows the maintenance of labor costs at the source at a level equal to or less than the labor cost required for prior art packaging, to equal number of prepared worms, while improving the quality.
